Retractable prong belt buckle



Sept. 7, 1965 R. SOKOLOFF RETRACTABLE PRONG BELT BUCKLE Filed Aprll 29, 1964 I M J p Fi W/l/II/AW United States Patent 3,204,314 RETRACTABLE PRONG B'ELT BUCKLE Raymond Sokoloif, 2245 Ocean Parkway, Brooklyn, NY. Filed Apr. 29, 1964, Ser. No. 363,380 1 Claim. (01. 24-188) This invention relates generally to the field of belt interconnecting devices, and more particularly to a retractable prong belt buckle suitable for use as an interconnecting means for a mans leather or Web'belt.

In belt buckles of this type, there is normally provided a D-ring having a generally rectilinear transverse portion which engages one end of the belt, and which mounts a pivotally arranged prong, the oppositely disposed free end of which is adapted to penetrate one of a plurality of holes in an opposite end of the belt, wherein upon the donning of the same, tension pulls the belt, which in turn moves the prong to engage a second portion of the D-ring element, to prevent further expanding movement.

Under certain conditions, it is often desirable to conveniently adjust the belt by enlarging the length thereof in a manner as unobtrusive as possible. With conventional belt buckles, this normally requires the grasping of the free end of the belt, and a further tightening of the same a degree sufiicient to disengage the free end of the prong with the presently engaged opening in the belt, and allowing the belt to slide through the D-ring element a degree sufficient to permit a different opening in the belt to be subsequently engaged. This operation also entails the manual outward movement of the prong element in order to permit its disengagement. Where the adjustment is performed while the wearer is in a sitting position, it calls for considerable manual manipulation, usually drawing considerable attention from those nearby.

It is among the principal objects of the present invention to provide an improved form of belt buckle which may be readily adjusted using the fingers of a single hand, and without the necessity of further tightening the belt prior to release.

Another object of the invention lies in the provision of an improved retractable prong belt buckle, in which the prong may be conveniently shortened against the action of a resilient means to permit the disengagement of the prong with a particular hole in the belt, and its subsequent engagement with an adjacent hole while the entire belt buckle is concealed beneath the hand of the wearer.

Another object lies in the provision of an improved retractable prong belt buckle possessed of the above advantages, in which the cost of fabrication may be of a reasonably low order, with consequent wide sale, distribution and use.

A feature of the invention lies in the fact that the inventive concept of the present disclosure may be incorporated into a wide variety of shapes and sizes of belt buckles by those skilled in the art to which the invention pertains.

Another feature of the invention lies in the fact that the device may be manufactured using existing techniques and tooling well known in the art.

These objects and features, as well as other incidental ends and advantages, will more fully appear in the progress of the following disclosure, and be pointed out in the appended claim.

In the drawing, to which reference will be made in the specification, similar reference characters have been employed to designate corresponding parts throughout the several views.

FIGURE 2 is a view in elevation thereof, showing the side opposite that seen in FIGURE 1.

FIGURE 3 is an enlarged longitudinal sectional view as seen from the plane 33 in FIGURE 1.

FIGURE 4 is a similar sectional view, but showing certain of the component parts in altered relative position.

FIGURE 5 is a view in elevation of an alternate form of the embodiment.

FIGURE 6 is an enlarged fragmentary sectional view, partly in elevation as seen from the plane 6-6 in FIG- URE 5.

In accordance with the principal form of the embodiment of the invention, the device, generally indicated by reference character 10 comprises broadly a pivotally mounted prong element 11 and a D-ring element 12, the same to be used in conjuction with a conventional belt of plastic, leather or webbing, generally indicated by reference character 13.

The prong element 11 includes a circular eye member 15, preferably formed by suitably bending metallic wire, and including a first or inner end 16 and a second or outer end 17 defining a circular opening 18, by means of which the prong element 11 is pivotally mounted on the D-ring element 12. Interconnected to the first end 16 is an elongated metallic sleeve 19 having first and second end openings 20 and 21, respectively leading to a continuous longitudinal bore 22. Extending through the body of the sleeve 19 is an elongated slot 23 which communicates with the bore 22 over a portion of the length thereof.

Positioned within the bore 22, and extending outwardly of the opening 21 is a prong member 24, the inner end 25 of which is provided with a finger engaging member 26 having a threaded portion 27 engaged within a correspondingly threaded bore 28. A coil spring 29 is disposed to contact the end 16 and the inner end 25 to urge the prime member 24 outwardly, or leftwardly as seen in FIGURE 3, outward movement being limited by contact of the finger engaging member 26 with the leftward end 30 of the slot 23.

The D-ring element 12 may be of any suitable conventional configuration, normally including an elongated transverse member 33 which mounts the eye member 15 in pivotal relation, a pair of longitudinal members 34 and 35 and an end member 36 which may be of either curved or rectilinear configuration as desired. As best seen in FIGURE 3, the end member 36 is preferably provided with a recess 37 for accommodating the outer end 38 of the prong member 24.

Referring to FIGURE 3, the belt 13 may be engaged with the device in a conventional manner, in which the prong member 24 projects through a desired opening 39. Where a quick release is desired, it is necessary only to move the finger engaging member 26 rightwardly as seen in FIGURE 4, wherein the end 38 clears the recess 37, and normal tension exerted on the belt causes the prong member 24 to pivot downwardly, wherein the free end of the belt 13 may be withdrawn through the opening in the D-ring element 12. If a mere adjustment of the belt is desired, it is necessary only to move the finger engaging member 26 rightwardly as seen in FIGURE 4, and to release the same when the desired opening 39 has been reached, at which point the end 38 re-enters another opening 39 to complete the adjustment. By placing the thumb of the user on the member 26, the fingers of the hand of the user may completely conceal the operation while adjustment is taking place, thus drawing a minimum of notice to the operation.

Turning now to the alternate form of the embodiment, illustrated in FIGURES 5 and 6 in the drawing, parts corresponding to those of the principal embodiment have been designated by similar reference characters with the additional sutfix a.

In the alternate form of the embodiment 10a, the member 34a is of selectively detachable construction, each free end thereof including a bore 33b having a spring 330 urging a pin 33d into a bore 33f at the extreme end 33g of the member 34a, this construction permitting removal and replacement of the prong element should the same, at any time, become necessary or desirable.

I wish it tobe understood that I do not consider the ine vention limited to the precise details of structure shown and set forth in this specification, for obvious modifications will occur to those skilled in the art to which the invention pertains.

I claim:
